l This invention relates to brushes and more particularly to a suctionbrush particularly adaptable to clean Venetian blinds and the like. Animportant object of the present invention is to provide a tool or deviceby means of which a plurality of substantially at surfaces may becleaned on both sides simultaneously.

Another object is that the device as set forth, is adaptable to'beattached to the suction hose of a vacuum cleaner or the like whereby thedust and the like is vraised by the brushing operation While the dust issucked or drawn by the hose of the vacuum cleaner.

Other apparent objects are the provision of a comparatively inexpensive,strong, durable and efficient article as set forth.

Broadly the invention comprises a hollow body portion to which areattached ra plurality of slightly curved lingers or arms kand acorresponding number of movable ngers or arms disposed immediatelyadjacent the rst mentioned fingers. A socket is also formed integrallywith the body as well as a carrying handle to operate the device.

Although the handle is shown as being separate from the socket, it mayeasily and without departing from the spirit of the present invention bepart of said socket. The socket referred to herein is that to which thesuction hose of a vacuum cleaner is attached to suck in the dustloosened by the bristles of the iixed and movable fingers.

All the movable ngers are connected to the body by means of a ball andsocket joint and they are all interconnected to each other and operatedby a single trigger or lever mounted on the handle of the device. Aspring is used to close the fingers when the pressure is released fromthe trigger.

With these and other objects in View that may appear while thedescription proceeds the invention consists in the novel arrangement ofparts as hereinafter more specifically set forth, claimed and shown inthe accompanying drawing forming part of this application and in which:

Fig. 1 is a perspective view of the invention and Fig. 2 is a fragmentalview showing how the movable fingers are mounted for operation.

Referring more in detail to the drawing in which similar referencecharacters designate corresponding parts throughout the several views,it will be seen the invention consists of a longitudinal rectangularhollow body 5 having each of its extremities t sealed, a plurality ofiixed fingers l also of hollow rectangular construction, a plurality ofmovable ngers 8 of similar construction to ngers l disposed adjacentsaid first mentioned fingers and a socket 9 on which is fastened thefree extremity of a vacuum cleaner suction hose. Bristles Il) aremounted on all fingers to loosen the dust and a plurality ofperforations Il through the fingers 'I and 3 suck in the dust.

The movable ingers 8 are attached to the body 5 and are mounted on aperforated ball l2 much like the common ball and socket joint. On ea-chmovable linger at a predetermined position from the joint is mounted arivet I3. To open the iingers in order to insert them over the slats ofa Venetian blind, a trigger M is provided and is mounted on the side ofthe handle I5 by means of a rivet I6.

A connecting rod il is slidably mounted on one of the vertical Walls ofthe body 5 and is loosely held in brackets I8.

A number of links i9 corresponding to the number of movable ngers areriveted to said connecting rod and extend therefrom in a lateraldirection. The outer extremity of each link is formed with alongitudinal slot 20. Said slot being disposed below the head and overthe body of rivets I3.

The extremity 2| of the trigger is formed with a. similar slot which isinserted over a rivet 22 on the connecting rod Il and when the triggeris Iurged upward it transmits a rearward motion to the connecting rod.This motion will force open all the movable fingers and then the deviceis inserted over a number of slats corresponding to the number offingers.

In order to return or close the movable fingers 8, the link I9a at therear extremity of the device extends above the connecting rod il' at 23and is formed with an aperture 2li. A coil spring 25 has one of itsextremities secured through said aperture and its other secured to arivet 26 mounted a distance ahead of the extension 23. The said spring25 will cause the fingers t to close when the trigger is released.

It is believed that the construction and advantages of the invention maybe apparent from the foregoing paragraphs taken in conjunction with theaccompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it isunderstood that minor changes in the construction and arrangement ofco-operating elements may be resorted to within the scope of what isclaimed Without departing from the spirit of the invention.

I claim: A

l. A device for cleaning Venetian blind slats comprising an elongatedhollow body having a socket for connection with a suction line, a seriesof spaced apart xed hollow arms extending laterally from and incommunication with said body, a series of hollow movable arms pivotallymounted to said body adjacent to said fixed arms and in communicationwith said body, said movable arms being capable of movement towards andfrom said fixed arms, said iixed and movn able arms having apertures intheir confronting faces, bristles mounted in the confronting faces ofsaid fixed and movable arms, a connecting bar mounted for longitudinalsliding movement on said body, a series of links extending laterallyfrom said connecting bar having pivotal 'connection with said movablearms, manual means for moving said connecting bar in one direction toswing said movable arms from said fixed arms and spring means for movingsaid connecting bar in the opposite direction to swing said mov-- ablearms towards said fixed arms.

2. A device or cleaning Venetian blind slats comprising an elongatedbody, a plurality of xed arms extending laterally from said body inspaced apart relation, a plurality of movable arms pivotally mounted tosaid body adjacent to said xed arms and movable towards and from saidiixed arms, a connecting bar slidably mounted on said body havingconnection with each of said movable arms, means for sliding said bar tomove said movable arms to closed and open position, said body and 'armsbeing of hollow construction with apertures in the confronting faces or"the fixed and movable arms, and means for connecting said hollow bodywith a suction line.

3. A device as described in claim 2 having ball and socket jointsconnecting said movable arms to said body.

4. .A device for cleaning Venetian blind slats comprising an elongatedbody, a plurality of fixed arms extending laterally from said body inspaced apart relation, a plurality of movable arms pivotally mounted tosaid body adjacent to said fixed arms and movable towards and from saidxed arms, said xed and movable arms being curved in a longitudinaldirection, bristles projecting from the confronting faces of said fixedand movable arms, a connecting bar slidably mounted on said body havingconnection with each of said movable arms, and means for sliding saidbar to move said movable arms towards and from said fixed arms.
